SAVCHGOBJ (Save Changed Object)

SAVCHGOBJ Command syntax diagram

 

Purpose

The Save Changed Objects (SAVCHGOBJ) command saves a copy of each changed object or group of objects located in the same library. When OBJ(*ALL) is specified, objects can be saved from all user libraries or from up to 300 specified libraries. When saving to a save file, only one library can be specified. For database files, only the changed members are saved. Objects or members changed since the specified date and time are saved.

Objects changed since the specified date and time are saved with the following exceptions:

Specified objects that were changed and the libraries where they reside remain locked during the save operation.

Saved objects can be restored with the Restore Object (RSTOBJ) command.

To determine the date and time that an object was changed, run the Display Object Description (DSPOBJD) command with DETAIL(*FULL) specified. For database file members that were changed, run the Display File Description (DSPFD) command.

The types of objects that can be saved by this command are listed for the OBJTYPE parameter in Commonly used parameters. The system saves the changed objects by writing a copy of each one on diskettes, tapes, optical volumes, or a save file. The description of each object is changed with the date, time, and place when it was last saved and is controlled by the UPDHST parameter.

Note: This command ignores all file overrides currently in effect for the job except for the save output file.

 

Restrictions

  1. To use this command, the user must have the special authority *SAVSYS specified in the user profile by the SPCAUT parameter. Otherwise, the user must have object existence authority for each object specified, and execute authority to both the specified library and the save file library. If the user does not have the necessary authority to a specified object, all changed objects except that object are saved.

  2. When saving to tape, diskette, or optical device, the user must have use authority to the device description. When saving to a save file, the user must have object operational and add authorities to the save file.

  3. When using a media definition, the user must have *USE authority to the media definition and *EXECUTE authority to the media definition library.

  4. All diskettes used to save the changed objects must be initialized in the save/restore format.

  5. If tape is used, a standard labeled volume designation must be used.

  6. No changed object that is being saved can be changed by a job that is running when the save operation occurs unless save-while-active is used.

  7. When the contents of a save file are being saved to the same save file by specifying SAVFDTA(*YES), only the description of the save file is saved.

  8. When the contents of a save file are saved with SAVFDTA(*YES), the save file must be restored before objects contained in it can be restored.

  9. When using the OUTFILE parameter to save to an existing database file, you must have execute authority to the output file library.

  10. Specifying USEOPTBLK(*YES) may result in a tape that can be duplicated only to a device that supports the same block size.

 

Required Parameters

OBJ
Specifies the names of one or more objects, or the generic names of each group of objects, to check for changes and then to save those objects that changed. All of the objects must be in the library specified on the LIB parameter.

If the OBJTYPE parameter is not specified, all the object types listed in the description of the OBJTYPE parameter are saved, provided they are in the specified library and have the specified names.

*ALL: All changed objects in the specified libraries are saved, depending on the values specified for the OBJTYPE parameter.

generic*-object-name: Specify a generic name. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk (*) substitutes for any valid characters. A generic name specifies all objects with names that begin with the generic prefix, for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete object name. For more information on the use of generic functions, refer to generic functions.

object-name: Specify the names of specific objects to save. Both generic names and specific names can be specified in the same command.

LIB
Specifies the name of the library that contains the changed objects to be saved.

*ALLUSR Libraries

generic*-library-name: Specify the generic name of the library. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk (*) substitutes for any valid characters. A generic name specifies all libraries with names that begin with the generic prefix, for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete library name. Up to 300 generic library names can be specified. A generic library name cannot be specified when saving to a save file. For more information on the use of generic functions, refer to generic functions.

library-name: Specify the name of the library to be saved. Up to 300 library names can be specified. Only one library can be specified when saving to a save file.

DEV
Specifies the name of the device on which the changed objects are saved. The device name must already be known on the system by a device description.

*SAVF: The save operation is done using the save file specified by the save file (SAVF) parameter.

*MEDDFN: The save operation is done using the devices and media identified in the media definition specified by the Media Definition (MEDDFN) parameter.

diskette-device-name: Specify the name of the diskette device used to save the objects.

optical-device-name: Specify the name of the optical device used for the save operation.

tape-media-library-device-name: Specify the name of the tape media library device used for the save operation.

tape-device-name: Specify the names of one or more tape devices used for the save operation. If multiple tape devices are specified, they must have compatible media formats and they are used serially in the order in which they are specified. Using more than one tape device permits one tape volume to be rewound and unloaded while another tape device processes the next tape volume. To use more than one device in parallel, a media definition must be specified.

 

Optional Parameters

OBJTYPE
Specifies the types of OS/400 system objects whose changes are saved. The object types saved are also the ones saved and restored by the Save Library (SAVLIB), Restore Object (RSTOBJ), and Restore Library (RSTLIB) commands. Data dictionaries and the associated files are saved only by using the SAVLIB command. More information on this parameter is in Commonly used parameters.

*ALL: Changes to all object types that are specified by name and that are in the specified library are saved. If *ALL is also specified on the OBJ parameter, changes to all objects in the libraries that are of the types shown in the list referred to are saved.

object-type: Specify the value for each of the types of objects that are saved, such as command (*CMD), file (*FILE), or program (*PGM).

OBJJRN
Specifies whether to save objects that are currently being journaled and that have been journaled since the date and time specified on the REFDATE and REFTIME parameters.

*NO: Objects being journaled are not saved. If journaling was started after the specified date and time, the changed objects or changed database file members are saved. The date and time of the last journal start operation can be shown by using the Display Object Description (DSPOBJD) command.

*YES: Objects whose changes are entered in the journal are saved.

REFDATE
Specifies the reference date. Objects in the specified libraries that have been changed since this date, and since the time specified in the REFTIME parameter, are saved.

*SAVLIB: Objects changed since the last running of the Save Library (SAVLIB) command are saved. If the specified library was never saved, a message is issued and the library is not saved, but the operation continues.

reference-date: Specify the reference date. Objects that have been changed since this date are saved. If you specify a date later than the date of the running of this command, a message is issued and the operation ends. The date must be specified in the job date format.

REFTIME
Specifies the reference time. Objects in the specified libraries that have been changed at or after this time are saved.

*NONE: No time is specified. Objects changed since the date specified on the REFDATE parameter are saved.

reference-time: Specify a time. Objects that have been changed since this time on the specified date are saved. If REFDATE(*SAVLIB) is specified, no reference time can be specified. The time is specified in 24-hour format with or without a time separator as follows:

  • With a time separator, specify a string of 5 or 8 digits, where the time separator for the job separates the hours, minutes, and seconds. If you issue this command from the command line, the string must be enclosed in apostrophes. If a time separator other than the separator specified for your job is used, this command fails.

  • Without a time separator, specify a string of 4 or 6 digits (hhmm or hhmmss) where hh = hours, mm = minutes, and ss = seconds. Valid values for hh range from 00 through 23. Valid values for mm and ss range from 00 through 59.


VOL
Specifies the volume identifiers of the volumes, or the cartridge identifier of a tape in a tape media library device, on which the data is saved. The volumes must be placed in the device in the order specified on this parameter. More information on this parameter is in Commonly used parameters.

*MOUNTED: The volume currently placed in the device is used. For a media library device, the volume to be used is the next cartridge in the category mounted by the Set Tape Category (SETTAPCGY) command.

Note: This value cannot be specified when using an optical media library device.

volume-identifier: Specify the identifiers of one or more volumes in the order in which they are put on the device and used. A blank is used as a separator character when listing multiple identifiers.

SEQNBR
Specifies, when tape is used, which sequence number is used as the starting point for saving changed objects.

*END: The system saves the changed objects starting after the last sequence number on the first tape. If the first tape is full, an error message is issued and the operation ends.

sequence-number: Specify the sequence number of the file. Valid values range from 1 through 16777215.

LABEL
Specifies the name that identifies the data file on the tape or diskette that is used for the save operation. If the LABEL parameter is used on the save command, the same label must be specified on the restore command.

*LIB: The file label is created by the system using the name of the library specified on the LIB parameter.

data-file-identifier: Specify the data file identifier (a maximum of 17 characters) of the data file used for the save operation. This option is valid only for the single-library save operations. Do not specify *SAVLIB; the system will return an error message if *SAVLIB is specified.

EXPDATE
Specifies the expiration date. The files cannot be overwritten until the expiration date. The expiration date must be later than or equal to the current date.

*PERM: The file is permanently protected.

expiration-date: Specify the date when protection for the file ends.

Note: For operations saving objects to diskette, the expiration date specified must be later than the date of the save operation. Otherwise, the unprotected save/restore files may be lost when the next save/restore file is written during the save operation.

ENDOPT
Specifies the operation that is automatically performed on the tape or optical volume after the save operation ends. If more than one volume is used, this parameter applies only to the last volume used; all other volumes are unloaded when the end of the volume is reached.

Note: This parameter is valid only if a tape or optical device name is specified on the DEV parameter. For optical devices, *UNLOAD is the only special value supported, *REWIND and *LEAVE will be ignored.

*REWIND: The tape is automatically rewound, but not unloaded, after the operation has ended.

*LEAVE: The tape does not rewind or unload after the operation ends. It remains at the current position on the tape drive.

*UNLOAD: The tape is automatically rewound and unloaded after the operation ends. Some optical devices will eject the volume after the operation ends.

STRLIB
Specifies the library with which to begin the *ALLUSR save. This parameter is used to recover from ended or failed *ALLUSR save operations.

Note: The user should not attempt to specify LIB(*ALLUSR) on a failed tape. The proper recovery procedure is to start over with a new tape, as if the user is starting the complete save operation again.

*FIRST: The save operation begins with the first library in alphabetical order.

library-name: Specify the name of the library with which to begin the save.

SAVF
Specifies the qualified name of the save file used to contain the save data. The save file must be empty or CLEAR(*ALL) must be specified.

The name of the save file can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

save-file-name: Specify the name of the save file used to contain the saved data.

MEDDFN
Specifies the qualified name of the media definition that identifies the devices and media used to contain the save data. For information about creating and using a media definition, see the Set up saves to multiple devices article in the Information Center.

Note: If a media definition is specified, the VOL, SEQNBR, SAVF, and OPTFILE parameters cannot be specified. The volume identifiers and sequence numbers are specified in the media definition.

The name of the media definition can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

media-definition-name: Specify the name of the media definition.

UPDHST
Specifies whether the save history information of each saved object is changed with the date, time, and location of this save operation. The save history information for an object can be displayed by using the Display Object Description (DSPOBJD) command. This information is used to determine which journal entries are processed when RCVRNG(*LASTSAVE) and FROMENT(*LASTSAVE) are used on the Apply Journaled Changes (APYJRNCHG) command.

*YES: The last save date, time, and location information is updated in each object saved.

*NO: The save history information contained in the description of each object saved is not updated.

Note: UPDHST(*NO) should be used for a save operation that is not intended for recovery. For example, if the save data is transmitted, record by record, to another system and the save file then deleted, the user probably does not want to update the save history information.

OMITLIB
Specifies the names of one of more libraries, or the generic names of each group of libraries, to be excluded from the save operation. If a value other than *NONE is specified then up to 300 values can be specified.

*NONE: No libraries are excluded from the save operation.

library-name: Specify the name of the library to be excluded from the save operation. Up to 300 library names can be specified.

generic*-library-name: Specify the generic name of the library. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk (*) substitutes for any valid characters. A generic name specifies all libraries with names that begin with the generic prefix, for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete library name. Up to 300 generic library names can be specified. For more information on the use of generic functions, refer to generic functions.

OMITOBJ
Specifies the objects to be excluded from the save operation. Up to 300 objects or generic object values can be specified.

If the OMITOBJ parameter is not specified, no objects are excluded from the save operation.

*NONE: No objects are excluded from the save operation.

Element 1: Object Name

The object name can be qualified by one of the following library values:

*ALL: The specified objects are excluded from all libraries that are part of the save operation.

generic*-library-name: Specify the generic name of the library. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk (*) substitutes for any valid characters. A generic name specifies all libraries with names that begin with the generic prefix, for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete library name. For more information on the use of generic functions, refer to generic functions.

library-name: Specify the name of the the library that contains the object to be excluded from the save operation.

*ALL: Objects in the specified libraries are excluded, depending on the value specified for the object type.

generic*-object-name: Specify the generic name of the object. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk (*) substitutes for any valid characters. A generic name specifies all objects with names that begin with the generic prefix, for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete object name. For more information on the use of generic functions, refer to generic functions.

object-name: Specify the name of the object that will be excluded from the save command.

Element 2: Object Type

*ALL: All object types are excluded from the save operation, depending on the value specified for the object name.

object-type: Specify the type of the object to be excluded from the save operation.

ASPDEV
Specifies the name of the auxiliary storage pool (ASP) device to be included in the save operation.

*: The operation includes the system ASP (ASP number 1), all basic user ASPs (ASP numbers 2-32), and, if the current thread has an ASP group, all independent ASPs in the ASP group.

*SYSBAS: The system ASP and all basic user ASPs are included in the save operation.

*CURASPGRP: If the current thread has an ASP group, all independent ASPs in the ASP group are included in the save operation.

auxiliary-storage-pool-device-name: Specify the name of the independent ASP device to be included in the save operation.End of change

TGTRLS
Specifies the release level of the operating system on which you intend to restore and use the object.

When specifying the target-release value, the format VxRxMx is used to specify the release, where Vx is the version, Rx is the release, and Mx is the modification level. For example, V5R2M0 is version 5, release 2, modification level 0.

Valid values depend on the current version, release, and modification level, and they change with each new release. See the Values for TGTRLS Parameter table in the Backup and Recovery book for a complete list of valid values.

To specify that an object be saved for distribution to a system at a different release level than the system on which the save operation is to occur, the procedure differs for program and non-program objects and by the release level on which program objects are created. If, for example, you are saving an object for distribution to a target system running on an earlier release, you have the following choices:

For program objects

  • If the program was created at a release level more current than the targeted earlier release, (1) create the program again specifying the targeted earlier release, (2) save the program specifying the targeted earlier release, and then (3) restore the program on the target system.

  • If the program was created at the same release level as the target system, you can (1) save the program specifying the targeted earlier release and then (2) restore the program on the target system.

For non-program objects

You can (1) save the object specifying the targeted earlier release and then (2) restore the object on the target system.

 

Notes

  1. If LIB(*ALLUSR) is specified, only the current release can be the target release.

  2. Not all objects can be targeted to another release. To find out which objects are supported, see the table in the Backup and Recovery book.

  3. Use the table in the Backup and Recovery book to find out the values that can be specified, and which release is specified when you choose the *CURRENT and *PRV values, on your operating system.

*CURRENT: The object is to be restored to, and used on, the release of the operating system currently running on your system. The object can also be restored to a system with any subsequent release of the operating system installed.

*PRV: The object is to be restored to the previous release with modification level 0 of the operating system. The object can also be restored to a system with any subsequent release of the operating system installed.

target-release: Specify the release in the format VxRxMx. The object can be restored to a system with the specified release or with any subsequent release of the operating system installed.

CLEAR
Specifies whether active data on the media is automatically cleared or replaced. Active data is any file on the media that has not expired. Clearing active data removes all files from the volume, starting at the specified sequence number for tape. Replacing active data on optical media replaces only the optical files created by this operation.

 

Notes

  1. Clearing a tape does not initialize it. You should initialize tapes to a standard label format before the save command is issued by using the Initialize Tape (INZTAP) command and specifying a value on the NEWVOL parameter.

  2. Clearing an optical volume does initialize it.

  3. Clearing a diskette does not initialize it. You should initialize diskettes to a save and restore format before the save command is issued by using the Initialize Diskette (INZDKT) command and specifying FMT(*SAVRST).

  4. If a volume that is not initialized is encountered during the save operation, an inquiry message is sent and an operator can initialize the volume.

*NONE: None of the media is automatically cleared. If the save operation encounters active data on a tape, diskette, or save file, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

*ALL: All of the media is automatically cleared.

If tapes are used and a sequence number is specified on the SEQNBR parameter, the first tape is cleared beginning at that sequence number. All tapes following that first tape are completely cleared. To clear the entire first tape, SEQNBR(1) must be specified.

*AFTER: All media after the first volume is automatically cleared. If the save operation encounters active data on the first tape or diskette, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file on the first volume, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

Note: The *AFTER value is not valid for save files.

*REPLACE: Active data on the media is automatically replaced. Optical volumes are not initialized. Tapes, diskettes, and save files are automatically cleared in the same way as the *ALL value.

PRECHK
Specifies whether the save operation for a library ends if all objects specified by this command do not satisfy the following conditions:

  • The objects exist

  • The objects were not previously found to be damaged

  • The objects are not locked by another job

  • The requester of the save operation has authority to save the objects

*NO: The save operation for a library continues, saving only objects that can be saved.

*YES: Ends the save operation for a library before any data is written if, after all specified objects are checked, one or more objects cannot be saved. If several libraries are specified, the save operation continues with the next library. However, if PRECHK(*YES) and SAVACT(*SYNCLIB) are specified and one or more objects in any library to be saved cannot be saved, the save operation ends and no objects are saved.

SAVACT
Specifies whether an object can be updated while it is being saved.

Note: If your system is in a restricted state, this parameter is ignored and the save operation is performed as if SAVACT(*NO) was specified.

*NO: Objects that are in use are not saved. Objects cannot be updated while they are being saved.

*LIB: Objects in a library can be saved while they are in use by another job. All of the objects in a library reach a checkpoint together and are saved in a consistent state in relationship to each other.

Note: Libraries with thousands of objects may be too large for this option.

*SYNCLIB: Objects in a library can be saved while they are in use by another job. All of the objects and all of the libraries in the save operation reach a checkpoint together and are saved in a consistent state in relationship to each other.

Note: If you specify this value and LIB(*ALLUSR), and many user libraries exist on the system, it can take a long time to reach a checkpoint for all of the objects and libraries in the save operation.

*SYSDFN: Objects in a library can be saved while they are in use by another job. Objects in a library may reach checkpoints at different times and may not be in a consistent state in relationship to each other.

Note: Specifying this value eliminates some size restrictions and may enable a library to be saved that could not be saved with SAVACT(*LIB).

SAVACTWAIT
Specifies the amount of time to wait for a commit boundary or an object that is not available, before continuing the save. If an object remains in use for the specified time, the object is not saved. If a commit boundary is not reached in the specified time, the save operation is ended.

120: The system waits up to 120 seconds for a commit boundary or an object before continuing the save operation.

*NOMAX: No maximum wait time exists.

wait-time: Specify the time (in seconds) to wait for a commit boundary or an object before continuing the save operation.

SAVACTMSGQ
Specifies the message queue that the save operation uses to notify the user that the checkpoint processing for a library is complete. A separate message is sent for each library to be saved when SAVACT(*SYSDFN) or SAVACT(*LIB) is specified. When SAVACT(*SYNCLIB) is specified, one message is sent for all libraries in the save operation.

This parameter can be used to save the objects at a known, consistent boundary to avoid additional recovery procedures following a restore operation. Applications can be stopped until the checkpoint processing complete message is received.

*NONE: No notification message is sent.

*WRKSTN: The notification message is sent to the work station message queue.

The name of the message queue can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

message-queue-name: Specify the name of the message queue.

ACCPTH
Specifies whether the logical file access paths that are dependent on the physical files being saved are also saved. The access paths are saved only in the case of the following:

  • All members on which the access paths are built are included in this save operation.

  • The access paths are not invalid or damaged at the time of the save.

The system checks to ensure the integrity of the access paths. Any discrepancies found by the system will result in the access paths being rebuilt.

Informational messages are sent indicating the number of logical file access paths saved with each physical file. All physical files on which an access path is built must be in the same library. This parameter does not save logical file objects; it controls only the saving of the access paths. More information on the restoring of saved access paths is in the Backup and recovery topic in the Information Center.

Attention!

If the based-on physical files and the logical files are in different libraries, the access paths are saved.

However, if the logical files and the based-on physical files are in different libraries and the logical files or physical files do not exist at restore time (such as during disaster recovery or the files were deleted) the access paths are not restored. They are rebuilt.

For the fastest possible restore operation for logical files, the logical files and the based-on physical files must be in the same library and must be saved at the same time.

*NO: Only objects specified on the command are saved. No logical file access paths are saved.

*YES: The specified physical files and all eligible logical file access paths over them are saved.

Note: Specifying this value does not save the logical files.

SAVFDTA
Specifies, for save file objects, whether the description of a save file, or both the description and the contents of a save file, are saved.

*YES: The description and contents of the save file are saved.

*NO: Only the description of a save file is saved.

DTACPR
Specifies whether data compression is performed.

*DEV: If the tape device has the hardware compression feature installed, processing proceeds as if DTACPR(*YES) is specified. If the compression feature is not installed or if save data is written to a diskette or save file, processing proceeds as if DTACPR(*NO) is specified.

Note: If *DEV is specified on both the DTACPR parameter and the COMPACT parameter, only device data compaction is performed if compaction is supported on the device. Otherwise, data compression is performed if supported on the device.

If *YES is specified on the DTACPR parameter and *DEV is specified on the COMPACT parameter, both device data compaction and device data compression are performed if supported on the device.

*NO: No data compression or decompression occurs.

*YES: If the save operation is to tape and the target device has the hardware compression feature, hardware compression is performed. If the feature is not present, or if the save data is written to optical, diskette, or save file, software compression is performed. If the save operation is being done while other jobs on the system are active and software compression is used, the overall system performance may be affected.

COMPACT
Specifies whether device data compaction is performed.

*DEV: Device data compaction is performed if the data is saved to tape and all tape devices specified on the DEV parameter support the compaction feature.

Note: If *DEV is specified on both the DTACPR parameter and the COMPACT parameter, only device data compaction is performed if compaction is supported on the device. Otherwise, data compression is performed if supported on the device.

If *YES is specified on the DTACPR parameter and *DEV is specified on the COMPACT parameter, both device data compaction and device data compression are performed if supported on the device.

*NO: Device data compaction is not performed.

OUTPUT
Specifies whether a list with information about the saved objects is created. The information can be printed with the job's spooled output or directed to a database file. The output or spooled print file does not include records for objects not changed.

*NONE: No output listing is created.

*PRINT: The output is printed with the job's spooled output.

*OUTFILE: The output is directed to the database file specified on the OUTFILE parameter.

Note: If OUTPUT(*OUTFILE) is specified, specify the database file name on the OUTFILE parameter.

OUTFILE
Specifies the qualified name of the database file to which the information about the object is directed when *OUTFILE is specified on the OUTPUT parameter. If the file does not exist, this command creates a database file in the specified library. If a new file is created, the system uses QASAVOBJ in QSYS with the format name QSRSAV as a model.

The name of the database file can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

database-file-name: Specify the name of the database file to which the output of the command is directed.

OUTMBR
Specifies the name of the database file member to which the output of the command is directed when OUTPUT(*OUTFILE) is specified.

Element 1: Member to Receive Output

*FIRST: The first member in the file receives the output. If OUTMBR(*FIRST) is specified and the member does not exist, the system creates a member with the name of the file specified on the OUTFILE parameter.

member-name: Specify the name of the file member that receives the output. If OUTMBR(member-name) is specified and the member does not exist, the system creates it. If the member exists, the user can add records to the end of the existing member or clear the existing member and add the records.

Element 2: Operation to Perform on Member

*REPLACE: The existing records in the specified database file member are replaced by the new records.

*ADD: The new records are added to the existing information in the specified database file member.

INFTYPE
Specifies the type of information printed or directed to the database file.

*OBJ: The list contains an entry for each object requested to be saved.

*ERR: The list contains information about the command, an entry for each library, and an entry for each object that was not successfully saved.

*LIB: The list contains an entry for each library requested to be saved.

*MBR: The list contains an entry for each object or, for database files, each member requested to be saved.

OPTFILE
Specifies the path name of the optical file that is used for the save operation, beginning with the root directory of the volume. For more information on specifying path names, refer to path names.

'*': The system generates an optical file name in the root directory of the optical volume.

'optical-directory-path-name/*': The system generates an optical file name in the specified directory of the optical volume.

'optical-file-path-name': Specify the path name of the optical file.

USEOPTBLK
Specifies whether or not the optimum block size is used for the save operation.

*YES: The optimum block size supported by the device is used for Save commands. If the block size that is used is larger than a block size that is supported by all device types then:

  • Performance may improve.

  • The tape file that is created is only compatible with a device that supports the block size used. Commands such as Duplicate Tape (DUPTAP) do not duplicate files unless the files are being duplicated to a device which supports the same block size that was used.

  • The value for the DTACPR parameter is ignored.

If the target release value that is specified is earlier than V3R7M0 then the block size supported by all device types is used.

*NO: The optimum block size supported by the device is not used. Save commands use the default block size supported by all device types. The tape volume can be duplicated to any media format using the Duplicate Tape (DUPTAP) command.
